I-Polyvinyl alcohol (PVA) powder iyi-polymer yokwenziwa encibilika emanzini enezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezihlukahlukene.Kuyinto eqondile, ye-polymeric eyenziwe nge-hydrolysis ye-polyvinyl acetate (PVAc).Izinga le-hydrolysis (DH) ye-PVA inquma ukuncibilika kwayo emanzini, ngamavelu e-DH aphezulu abonisa ukunyibilika okuphezulu.I-PVA powder itholakala kumabanga ahlukahlukene, kuye ngenani le-DH nesisindo samangqamuzana.

Izakhiwo ze-PVA powder PVA powder zinezici ezimbalwa eziyingqayizivele ezenza kube ukukhetha okudumile ezinhlelweni eziningi.Ezinye zalezi zakhiwo zihlanganisa:

1. Ukuncibilika kwamanzi: I-PVA powder incibilika kakhulu emanzini, okwenza kube lula ukuncibilika emanzini ukuze kwakheke isixazululo esicacile.
2. Ukwenza ifilimu: I-PVA powder ingakha ifilimu ecacile, eguquguqukayo, futhi eqinile uma incibilika emanzini bese yomiswa.
3. Ukunamathela: I-PVA powder inganamathela ezindaweni ezihlukahlukene, ikwenze kube ukukhetha okuthandwayo kokunamathelayo.
4. I-Biodegradability: I-PVA powder i-biodegradable, okusho ukuthi ingaphulwa ngezinqubo zemvelo.

Izicelo ze-PVA powder

1. Ama-Adhesives: I-PVA powder ivame ukusetshenziswa njengengxenye eyinhloko kuma-adhesives.Isetshenziselwa ukukhiqizwa kweglue yokhuni, iglue yephepha, nezinamatheliso zendwangu.I-PVA Adhesive ifaneleka ukuhlanganisa izindawo ezinezimbotshana, njengephepha, amakhadibhodi nokhuni.
2. Ukupakisha: I-PVA powder isetshenziswa ekukhiqizeni izinto zokupakisha ezifana namafilimu nezingubo.Ifilimu eyakhiwe ngempushana ye-PVA inamandla aqinile aqinile, izindawo ezinhle zokuvimbela igesi, nokucaca okuhle kokubona.
3. Imboni yezindwangu: Impushana ye-PVA isetshenziswa embonini yendwangu ukukhiqiza ama-sizing agents entambo nezindwangu.Isetshenziselwa ukwandisa amandla nokuqina kwentambo noma indwangu, okwenza kube lula ukuluka nokuphatha.
4. Imboni yamaphepha: I-PVA powder isetshenziswa embonini yephepha njengesengezo sokugcina esimanzi.Isetshenziselwa ukuthuthukisa amandla, ukumelana kwamanzi, nokuphrinta kwephepha.
5. Imboni yokwakha: I-PVA powder isetshenziswa embonini yezokwakha njengesibophezelo sikasimende nezinye izinto zokwakha.Ibuye isetshenziswe njengokwemboza izindawo ezikhonkolo ukuze kuthuthukiswe ukumelana kwazo namanzi.
6. Imikhiqizo yokunakekelwa komuntu siqu: Impushana ye-PVA isetshenziswa emikhiqizweni yokunakekelwa komuntu siqu njengezifutho zezinwele, ama-shampoos, namajeli.Isetshenziswa njengefilimu-yangaphambili kanye ne-thickener ukuthuthukisa ukuthungwa nokusebenza kwale mikhiqizo.
7. Imboni yezokwelapha: I-PVA powder isetshenziswa embonini yezokwelapha ukukhiqiza ama-hydrogel, ukugqokwa kwamanxeba, nezinhlelo zokulethwa kwezidakamizwa.I-biocompatibility kanye nokuncibilika kwamanzi kwe-PVA kuyenza ibe into efanelekile yalezi zinhlelo zokusebenza.

Izinhlobo ze-PVA powder PVA powder zitholakala emabangeni ahlukahlukene, kuye ngokuthi inani layo le-DH nesisindo samangqamuzana.Inani le-DH le-PVA powder lihluka kusuka ku-87% kuya ku-99%.Lapho inani le-DH liphakeme, i-PVA powder iyancibilika kakhulu emanzini.Isisindo samangqamuzana e-PVA powder sisukela ezinkulungwaneni ezimbalwa kuya ezigidini ezimbalwa.

1. I-PVA powder egcwele i-hydrolyzed: Lolu hlobo lwe-PVA powder lunenani le-DH lika-99% noma ngaphezulu.Incibilika kakhulu emanzini futhi inezinto ezinhle kakhulu zokwenza ifilimu.Isetshenziswa kakhulu ezintweni ezifana nama-adhesives, ukupakisha, nezindwangu.
2. I-PVA powder ingxenye ye-hydrolyzed: Lolu hlobo lwe-PVA powder lunenani le-DH elisukela ku-87% kuya ku-98%.Ayincibiliki emanzini kunempushana ye-PVA ene-hydrolyzed ngokugcwele futhi inezakhiwo eziphansi zokwenza ifilimu.Ivame ukusetshenziswa ekusetshenzisweni okufana nephepha nokwakhiwa.
